MONROVIA, Liberia (Reuters) -- Soccer star George Weah's party has demanded a rerun of Liberia's presidential runoff vote, saying the poll he appeared to have lost was unfair.Weah supporters hurled stones at police on Friday and United Nations police used tear gas and batons to disperse hundreds of people protesting at the U.S. embassy in Liberia's capital Monrovia but the city appeared calm on Saturday.With 97 percent of polling stations' votes counted from Tuesday's runoff ballot, Harvard-trained former Finance Minister Ellen Johnson-Sirleaf has an unassailable 59.4 percent and looks set to become Africa's first elected woman president, but former AC Milan striker Weah has cried foul."The process was unfair. There is a difference between free and fair elections," Milton Teahjay, senior political advisor to Weah and his Congress for Democratic Change (CDC) party, told Reuters on Saturday."We are asking for a rerun of the election," he said.Weah's party says Tuesday's election was marred by serious irregularities including doctored ballot papers, even though international observers gave it a generally clean bill of health and urged all parties to respect the result.African Union commission head Alpha Oumar Konare, a former president of nearby Mali, issued a statement on Saturday calling "on the candidates to accept the results of the polls as a clear expression of the will of the people of Liberia."Weah's CDC has filed an application to the country's Supreme Court to try to stop the counting process, now in its final stages, but the court told Weah's campaign team it could not consider the complaint until the National Elections Commission (NEC) had investigated it.A transitional government formed two years ago to draw a line under 14 years of civil war urged Weah and the CDC to restore calm after Friday's violence."Government deems such mob and unruly action as a serious violation of the law and therefore completely unacceptable," the government said in a statement.Weah appealed for calm in broadcasts on several local radio stations and asked his supporters to go home, the CDC's national campaign manager Jacob Kabakole told Reuters.Alan Doss, head of the 15,000-strong U.N. peace mission in Liberia, spoke to Weah about Friday's trouble, UNMIL said in a statement."UNMIL reiterates that it will deal firmly and decisively with any attempts, by any persons, who would seek to use violence to derail the elections process or to undermine peace or public order," it added.Copyright 2005 Reuters.
